Volcanic islands can seem to appear out of nowhere, emerging from the ocean like breaching monsters of the deep. Below, Mika McKinnon explains how these odd geological formations are born, how they evolve, and how they eventually vanish back beneath the waves.

Matthew Richmond's curator insight, December 2, 2015 8:30 PM

Re-scooped from Professor Dixon, pretty cool story on the formation of islands in the south Pacific. A couple of them look like the island visible from the beach in Rincon, Puerto Rico where I stayed. The island is one giant rock so nobody lives there and it's a naval base for the U.S. military. This, however, is a different situation when you realize that not only do people live here, but kind of a lot of people live here.

What causes the death and the caldera in a volcano? One thing that happens in a deceased volcano is the center of the volcano starts to either erode or the inside finally caves in. Once this happen a caldera takes shape and the ocean starts to take over. As the waves eat away at the shores it will eventually create a island that is shaped like a "U". After this happens that island will someday retreat back into the ocean and someday form a barrier reef.

Adam Deneault's curator insight, December 15, 2015 3:52 AM

Based on general knowledge, I know that the taller a volcano is, the younger it is and the shorter it is, the older it is. The reason they start to get short is from erosion. Hot spots in the Earth's crust make small islands from molten rock. Young islands can be very dangerous, because if they are inhabited, they have the possibility of erupting, whereas an old island does not since the volcano is lnactice and eroding. Over time the inactive volcano will crumble and a caldera will take shape and after even more time, that caldera will slip under the ocean and become a reef.

Jake Red Dorman's curator insight, November 13, 2014 3:50 PM

Air travel was almost all in code red when Iceland’s volcano Bárðarbunga and Papa New Guinea’s volcano Tavurvur erupted at the same time one day. All of Europe was in code red and also the Middle East, East Asia, Southeast Asia, South Asia, Australia, Russia, parts in Africa, and even in parts of South America. All other places such as the United States, United Kingdom and Canada were all in code orange. I’m not sure if this happened by coincidence since Papa New Guinea’s volcano is very active or that it is somehow connected, But I was looking at the tectonic plates and it doesn’t seem like they are connected, but there are plate lines located exactly where the volcanos are. I am guessing this happened dues to both of those plates moving at the same time, creating a simultaneous eruption.
